Broadcom NetXtreme and NetXtreme II TOE 3
This document provides important information about installing Broadcom NetXtreme and NetXtreme II
drivers and also describes known limitations of the driver set under various conditions. For further
information about the Broadcom drivers, see the ReadMeFirst.txt file on the driver CD or in the
downloadable Broadcom driver package.
This document also provides information about installing and enabling the TCP/IP Offload Engine
(TOE) feature on your system and provides important information about using TOE. For information
on setting up the Microsoft
®
Windows
®
operating system to work with Broadcom NetXtreme devices
and the TOE feature, see the engineering brief on support.dell.com entitled "Best Practices for
Installation of Microsoft Windows on Dell™ Servers With Broadcom NetXtreme Devices."
Installing the Broadcom Drivers in Microsoft Windows
To install the Broadcom driver package (NetXtreme version 8.3 or later and NetXtreme II version 2.6 or
later), run the setup.exe file that is provided on the Broadcom Driver Installation CD that shipped with
your system. The setup.exe file is located in the Driver_Management_Apps_Installer directory under
the directory of the version of Microsoft Windows you are using.
The Broadcom setup.exe utility is also available on the Service Mode CD of Dell Server Assistant (DSA)
or can be downloaded as a compressed file from support.dell.com.
Using the setup.exe file is the preferred method for installing the drivers on a local system. All of the
available package features are installed by default using this method. If you need to install the drivers
using the Windows Plug and Play method, you can extract the drivers from the installer file by running
setup.exe /a and specifying a directory for the extracted files.
Requirements for TOE
The following hardware and software components are required to use TOE on your TOE-capable system:
• Broadcom NetXtreme II 5708-based networking device, drivers, and control suite software.
• Microsoft Windows Server
™
2003 operating system family (32-bit or 64-bit) updated to Service Pack 1
or later.
• Microsoft Windows Server 2003 Scalable Networking Pack (SNP) hotfix. (For more information on
the SNP hotfix, see
Knowledge Base Article 912222 available on the Microsoft support web site.)
The TOE-capable Broadcom 5708-based networking devices are offered as integrated LAN-on-
Motherboard (LOM) and as an add-in PCIe adapter. The 5708-based LOM network devices on some
systems also require a license-enabling hardware key; see your system documentation for the location
and proper installation of this hardware key on your system board.
4 Broadcom NetXtreme and NetXtreme II TOE
Installing and Enabling TOE
If the Microsoft Windows operating system was installed on your system using your system management
software, you only need to update the operating system and drivers with the files necessary to support
TOE. To update your system, insert the TOE Update Installation CD and double-click the icon on
the Windows desktop entitled install-TOE-Update.vbs to start the update script. Follow the on-screen
instructions to install the SNP hotfix and the Broadcom tools to support TOE.
If the install-TOE-Update.vbs script is not available on your system, you must install the Broadcom
driver package and the Microsoft SNP hotfix in separate steps. If you have not already done so, install
the Broadcom driver package by running the setup.exe file included in the Broadcom driver package.
See "Installing the Broadcom Drivers in Microsoft Windows" earlier in this document for more
information.
NOTE: Features of the driver package can be deselected, but you must install the Broadcom Advanced
Control Suite (BACS) as you will need this application to configure and control TOE offload settings.
The SNP hotfix is provided on the TOE Update Installation CD; you can also download the hotfix from
the Microsoft support web site. Begin the installation by double-clicking the hotfix executable file and
following the on-screen instructions.
TOE is enabled by default once all the required components are installed. To disable TOE or change
the settings, use the Broadcom BACS software. For information on using BACS, see the Broadcom
NetXtreme II User’s Guide available on the Broadcom Driver Installation CD.
Windows Remote Installation Services and Unattended
Installation
A specialized driver is provided to enable complete Remote Installation Services (RIS), PXE, and ADS
installation of all the drivers and applications in the Broadcom driver package. To use the RIS driver,
browse the
Broadcom Driver Installation CD
and
locate the directory for your operating system.
Copy
the
RIS driver and .inf file located in the directory to the i386 image directory on your RIS server and then
restart the RIS services. The RIS driver and .inf file are also available in the
Windows driver package,
which can be downloaded from
support.dell.com
.
To install the Broadcom driver package with ADS, you must copy the RIS driver and .inf files into
one or more locations of the ADS image file to properly set up the remote installation. See the ADS
documentation for instructions on where to place the driver files in ADS.
Once the driver files have been copied into the server image, you can proceed to install the Broadcom
driver package using remote services. The recommended method for installing the drivers with remote
services is first to extract the drivers from the installer file by running setup.exe /a and then set up
the remote installer answer file to install the drivers using the Windows Plug and Play wizard. Installing
the drivers as a separate step ensures that all required drivers are installed to support the Broadcom
network controllers.

Broadcom NetXtreme and NetXtreme II TOE 5
The remainder of the Broadcom driver package, which includes the management software, Broadcom
Advanced Control Suite (BACS), is installed after the remote service installs the operating system.
The Broadcom setup.exe installer file can be set up to run from the post-installation portion of the
unattended answer file. For more information on how to use the unattended answer file, see the
Microsoft Windows Corporate Deployment Tools User’s Guide. For information about unattended
installation options specific to the Broadcom driver package, see the silent.txt file located on the
Broadcom Driver Installation CD
in the same directory as the setup.exe file. Additional information on
adding a network adapter to a RIS installation is available in Microsoft Knowledge Base article 315279.
NOTE: Network configuration parameters cannot be set in the unattended answer file using the PCI
Bus/Device/Function field. You must use the MAC address field to specify the interface to receive the network
settings.
To further customize your RIS installation to assign IP addresses and other network settings, you can use
WMI scripts in the post-installation phase of the unattended answer file.
Microsoft also provides the program netset.exe in the Windows 2000 Server Resource Kit. Netset.exe
uses the unattended answer file to apply network settings specified in the answer file to network
connections that failed to properly receive those settings during installation. For more information on
netset.exe, see the Microsoft Windows 2000 Server Resource Kit, or see the Microsoft Knowledge Base
article 268781.
Firewalls and TOE
Installing or activating firewall applications disables TOE for all TOE-enabled NICs in a system.
A firewall application must examine all incoming packets and frames to implement its protection
mechanisms. This firewall function is incompatible with the packet-offload operation of TOE.
Windows Network Bridging, VPN, and Routing With TOE
If you enable certain networking components in Windows like VPN, bridging, or routing services,
the Windows operating system also enables IP NAT and IPSEC Policy Agent by default. TOE will not
function with these services and disabling these services is not enough to re-enable TOE. You must turn
off IP NAT and IPSEC Policy Agent before TOE will function. Use the following commands at a
command prompt to turn off IP NAT and IPSEC Policy Agent.
net stop accesspolicy <Enter>
net stop sharedaccess <Enter>
net stop ipnat <Enter>
6 Broadcom NetXtreme and NetXtreme II TOE
Linux High-Stress Environments Running Multiple NetXtreme II
Adapters
In high-stress Linux environments running multiple NetXtreme II NICs, the Broadcom 5708 network
connection may run out of receive buffers. The default receive descriptor ring size for a 5708 connection
is 100. If network traffic shows excessive dropped packets and connection timeouts, increase the size
of the receive description ring using the following command string.
ethtool -G ethn rx size
where n is the number of the Ethernet channel and size is the new size of the receive description ring.
The following example changes the receive ring size for eth0 to 400:
ethtool -G eth0 rx 400
When prompted to verify the change, enter the following command:
ethtool -g eth0
To make the updated receive descriptor ring setting permanent, do the following:
• For Red Hat
®
Linux
®
, add the
ethtool
entry to
/etc/rc.d/rc.local
.
• For SUSE
®
Linux, perform the following procedure:
a
Add the following to the interface configuration file in
/etc/sysconfig/network
.
POST_UP_SCRIPT=set_ring_size
b
Create a
set_ring_size
script file with the following commands and place it in
/etc/sysconfig/network/scripts
.
#!/bin/bash
ethtool –G ethn rx size
where
n
is the number of the Ethernet channel and
size
is the new size of the receive description
ring.
c
Make the script executable by running the following command:
chmod +x set_ring_size
Broadcom NetXtreme and NetXtreme II TOE 7
Running Diagnostics in Microsoft Windows
The first time you run the Broadcom diagnostics program on NetXtreme II (5708) devices in a Microsoft
Windows environment, the Windows operating system will automatically install the diagnostics driver
for the program. You may be prompted during the driver installation to specify the directory location
of the driver, bxdiag.inf. Specify the directory where you unzipped the Broadcom driver package.
If the file bxdiag.inf does not exist on your hard drive, you can run the Broadcom Installer setup.exe
from the zip package included on the DSA Service Mode CD, or from the zip package downloaded from
support.dell.com. Running the installer will place the diagnostic driver on your hard drive and prepare
it for automatic installation for when you run the Broadcom diagnostics program.
